Displacement-Time Graph

Displacement-Time Graph

In a displacement-time graph, we can determine

  1. The displacement of the oscillating object at any time.
  2. The amplitude
  3. The period.


Figure above shows a displacement versus time graph for a vibrating object.
  1. Find the amplitude, period and frequency for the vibrating system.
  2. What is the displacement of the object at t = 0.3 s,
  3. Sketch in the same axis above, a graph of a wave which the frequency and amplitude are half of the wave in the figure above.

The amplitude, A = 10cm
The period, T = 0.4s
The frequency,
f= 1 T f= 1 0.4 =2.5Hz

b. The displacement at 0.3s = -10cm
